The major results of the questionnaire study revealed that most of the children were in the lower elementary grades, the distribution of IQs contained a larger proportion with below average ability than is found in the general population of children. Concerns about the ability-achievement discrepancy method for specific learning disability (SLD) determination led to alternative research-based methods, such as failure to respond to intervention.
